MinT - Best Known (220−135, 220, s)-Nets in Base 3

Best Known (220−135, 220, s)-Nets in Base 3

(220−135, 220, 60)-Net over F₃ — Constructive and digital

Digital (85, 220, 60)-net over F₃, using

net from sequence [i] based on digital (85, 59)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 59)-sequence over F₉, using
  - s-reduction based on digital (13, 63)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 13 and N(F) ≥ 64, using
      - a function field by GarcÃa and Quoos [i]

(220−135, 220, 84)-Net over F₃ — Digital

Digital (85, 220, 84)-net over F₃, using

t-expansion [i] based on digital (71, 220, 84)-net over F₃, using
- net from sequence [i] based on digital (71, 83)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 71 and N(F) ≥ 84, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(220−135, 220, 404)-Net in Base 3 — Upper bound on s

There is no (85, 220, 405)-net in base 3, because

1 times m-reduction [i] would yield (85, 219, 405)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 319 036554 553517 531333 834933 574544 089329 553183 519810 923639 457661 534844 494355 412446 609989 781952 816283 853227 > 3²¹⁹ [i]
